I would have to question your understanding of the term "end to end" if you're make such an assertion. > > There is no end to end IPv6 or for that matter IPv4 delivery today across any > network.

If your assertion was true about IPv6, then you are asserting that literally every IPv6 packet is going through NAT66 at some point.
